The Clarity E814 amplified corded phone bundled with the D703HS amplified cordless handset offers you all the benefits of both phones at the same time. These phones amplify incoming sound up to 40 dB and have 4 tone settings to customize your listening experience. Both units include large, high-contrast CID displays, large keypads with high-contrast numbers, 5 speed dial buttons, and extra loud and clear speakerphone for hands-free conversations. The amplified digital answering machine makes it easier to listen to messages, and the CID displays light up as super bright visual ringers.
